Watermarking to Replace DRM? 365
An anonymous reader writes "News.com has an article on the announcement of Microsoft and Universal to introduce watermarking technology into audio files. The technology could serve several purposes including tracking file sharing statistics and inserting advertisements into audio tracks. The article goes on to suggest that watermarking could possibly replace DRM in the near future."

Watermarking is quite frankly fantastic. If these companies are moving to watermarking instead of DRM then more power to their balance books! I'm not interested in downloading music or movies.

Watermarking doesn't stop me from doing anything I'm legitimately allowed to do so if it satisfies their requirements to go and catch people who do make illegitimate copies, then I would very much like them to use Watermarking. Hopefully it will lead to more products that I can buy online.

I posted a comment at news.com with basically the same idea.
If the bits and bytes can be adjusted in an undetectable manner to put a watermark on, say, an audio or video file, why can't someone just come along after and adjust the bits and bytes again in some random manner to effectively erase the watermark? I mean, if they can't read the bits and bytes that they put on the media because they've been altered, they wouldn't be able to track it, and the watermark would pretty effectively be broken.
It just seems to me that although having a bit-for-bit identical copy of the original would be nice, they've already altered it so that we can't get that. Altering it a bit more (no pun intended) wouldn't really be harmful, and it would still meet the end goal of distributing the media untraceably.
But you're right, another option would be to have two (three? four?) accounts get multiple copies of the same file and do a bit-by-bit comparison, either averaging the differences or picking from one of the two copies at random. If you have multiple copies, you might even be able to derive a highly probable copy of the original.

It's likely that someone with a lot of technical knowledge will be able to remove watermarks, it's also true that a person with a lot of technical knowledge will be able to bypass DRM. Someone who's serious about distributing copyrighted material will be able to find a loophole somewhere, and the only realistic purpose of a DRM scheme or watermarking scheme is to discourage casual sharing.
Even though people will find a way to remove this watermarking, most people won't bother to figure out how to do it. It might succeed at discouraging casual file sharing without impeding customers from using the content they've purchased.
